Abstract

A tensioner for tensioning flexible drives employs an extruded shaft which can provide a relatively complex cross sectional shape to provide anti-rotation features to inhibit rotation of a pivot bushing located on the shaft. The pivot bushing has a frustoconical outer shape, as does the pivot surface of the hub of the tensioner arm which pivots on the pivot bushing. A dampening spring urges the pivot bushing towards the tensioner arm's pivot surface, providing for wear compensation and for dampening. The degree of dampening which is generated between the pivot bushing and the tensioner hub can be selected in a variety of manners: by varying the spring force; by changing the effective contact surface area between the pivot bushing and pivot surface; and/or by changing the coefficient of friction between the pivot bushing and the pivot surface.
